ABSTRACT:
A hydraulic system having a plurality of motor driven pumps in parallel legs, at least one being active and one in reserve, so combined with sensors to sense pump efficiency and filter efficiency that a condition deemed pump failure or filter failure results in activating the reserve leg and deactivating the inefficient leg. Other sensors detect flow meter failure and establish warnings of conditions deemed near-failure. The system may be duplicated both on the pressure side and return side of the pumps. The system reservoir is characterized by a tank for return fluid to be cleaned and a separate tank for the fluid to be delivered under pressure; so constructed as to (a) remove turbulence, (b) prevent vortex overlap, (c) remove silt fines and (d) maintain a proper pumping level.
